After School's Nana goes topless in third teaser photo for "First Love"

After School isn't done teasing yet, as they've just revealed another photo of Nana, who seems to have misplaced her top!

Providing quite the visual with this latest teaser, the group asks you "What's Next?", leaving us curious to see what else they have in store before their return!

We still have a bit of wait as "First Love", their title track and the product of Brave Brothers, won't be revealed until the 13th. 

As mentioned earlier, despite the emotional and sorrowful nature of the topic of the song, the ladies are planning to present you with a performance of a completely different feel as they pour in their all to prepare stages that will have you thinking of a Las Vegas show with its performance quality.

So hang tight until the release!
